Improvement in sash-holders



UNErE prn'rEs PATENT OEEICE.

CHARLES RICH, OF WINCHESTER, NEW HAMPSHIRE.

IMPRQVEMENT 1N sAsH-HoLDERs.

To all whom it may concern:

Beit known that I, CHARLEs RICE, of Winchester, of the county of Cheshire and State of New Hampshire, have invented a new and useful Improvement in Supporting the Sashes of Windows; and do hereby declare the same to be fully described in the following specifi'- eation and represented in the accompanying drawing, of which- Y Figure l denotes a front elevation, Fig. 2 avertical and transverse section, and Fig. 8 a horizontal section of a window-frame and two sashes provided with my invention. Fig. 4 is a horizontal section of the window-frame without the sashes.

In carrying out my invention as shown in I the said figures, I line either or each side of each of the sash-receiving grooves of the window-frame with a strip, a, of India rubber, so as to constitute an elastic and friction cushion for the sash to bear against.

In the drawing, A denotes the window-frame and B C its two sashes. Each of these sashes, as represented, is provided at its vertical edge with a tongue, b, to extend into a groove of the window-frame. The grooves in the said window-frame are shown at e, those of each side of the frame being in opposite sides f a xed or stationary rib or part, h, having its opposite surfaces re-enforced or lined with strips a a of India rubber. The opposite part of each groove is a movable flexible strip, d or d', held in place by staples e e e arranged against itiand in the window-frame, in manner as shown or by other suitable means. A clamp-screw, D, formed and arranged in the window-frame, in manner as represented, has its head f lapped upon one of the strips, (viz., d,) and where the screw extends from the window-frame it is provided with a clampnut, E, to bear against a semieircular abutment, F, projecting, as shown, from the other strip, d.

On setting up the nut the two elastic strips d d will be drawn simultaneously toward each other, so as to clamp the window-sashes in their grooves with the requisite degree of friction, either to support one or both'when at any desirable altitude in the frame, or to practically hold each or both so las to render it difficult, if not impossible, to move such either upward or downward. If desirable, such a clamp screw and nut may be so applied to each pair of upright bars or strips d d; but it will suffice, generally speaking, to apply them to one pair only.

The sill h and cup-bar i of the window-frame have tongues k 7c arranged in them, as shown, to enter corresponding grooves Z l made in the sashes, such grooves being lined with India rubber, as shown at m, the rubber-lining operating in connection with the next adjacent tongue to prevent dust or air or water from passing between the sash and the frame. The linings of the frame-grooves also serve to exclude air, dust, and water.

My invention is specially valuable for the windows of railway .passengercarriages, it doing away with all necessity of supporting either sash by cords and balance-weights.

I make no claim to any thing, combination, or arrangement shown or described in either of the United States Patents 72,128, 81,850, 108,443, in neither of which are found the rubber strips or cushions a a to the parting bars or ribs l1. h. Neither do we find, in such patents, the abutment F or the tongues k and the rubber-band grooves b to the window-frame and the sashes, as in my case.

I therefore claim- The window-frame A, as provided withthe sashes B C, the rubber strips or friction-cushions a, the parting-bars h, and also with the exible supporting-strips d d', and the screwclamp D, and nut E, all arranged as set forth.

u CHARLES RICH.
